- <h1>JSP 2.0 Examples - jsp:attribute and jsp:body</h1>
- <hr>
- <p>The new <jsp:attribute> and <jsp:body>
- standard actions can be used to specify the value of any standard
- action or custom action attribute.</p>
- <p>This example uses the <jsp:attribute>
- standard action to use the output of a custom action invocation
- (one that simply outputs "Hello, World!") to set the value of a
- bean property. This would normally require an intermediary
- step, such as using JSTL's <c:set> action.</p>
- <br>
- <jsp:useBean id="foo" class="jsp2.examples.FooBean">
- Bean created! Setting foo.bar...<br>
- <jsp:setProperty name="foo" property="bar">
- <jsp:attribute name="value">
- <my:helloWorld/>
- </jsp:attribute>
- </jsp:setProperty>
- </jsp:useBean>
- <br>
- Result: ${foo.bar}
